~x-ai/grok-latest → A (3:1)

A cleanly relocates the 1800-line parser into server/src/ (new parser.rs + parser_action.rs + parser_render.rs), wires it into ui_html.rs/home + static JS + tests, and deletes the legacy copy. B pastes the identical parser.rs at the repo root plus ~4000 lines of unrelated reducer/ranking/seed files and malformed pastes, creating duplication and noise with no integration.
